Hitachi-Sumitomo SCX2500LF

The Hitachi-Sumitomo SCX2500LF is a high-capacity crawler crane with a maximum lifting capacity of 250 tons at a 4.5-meter working radius, making it suitable for heavy-duty construction, infrastructure, and industrial projects. The crane’s basic boom length starts at 15.25 meters, extendable to a maximum length of 88.4 meters. For additional reach, a fly jib can be added, with lengths ranging from 12.20 to 36.55 meters, resulting in a total combined boom and jib length of up to 124.95 meters (88.4 meters + 36.55 meters), providing versatility for high-reaching tasks.

In luffing towercrane configuration, the SCX2500LF offers tower lengths from 21.35 meters to 60.95 meters, paired with a luffing jib length of 60.95 meters. This setup allows for precision lifting at significant heights and in confined spaces, making it ideal for urban construction or complex industrial environments.

The crane’s rope line speeds are designed to optimize lifting performance. The front and rear main drums feature adjustable speeds from 120 meters per minute to 2 meters per minute, providing efficient handling of heavy loads. The boom hoist drum operates at a speed of 24 meters per minute, while the luffing jib hoist drum reaches speeds up to 50 meters per minute in towercrane configuration, allowing for rapid and controlled lifting operations.

The SCX2500LF is equipped with a slewing speed of 1.7 rpm, which ensures smooth and precise rotational movement for positioning loads. The crane’s travel speed is adjustable between high (1.2 km/h) and low (0.8 km/h), allowing it to navigate various job site conditions efficiently. Its gradeability is rated at 30%, providing stability and reliable operation on inclined surfaces.

The crane is powered by a Mitsubishi 6D24-TL diesel engine, which produces a rated output of 235 kW at 2,000 rpm. This four-cycle, water-cooled, turbocharged engine with intercooler ensures sufficient power for demanding lifting tasks while meeting current emission standards. The engine’s design also supports efficient fuel consumption, enhancing the crane’s operational cost-effectiveness.

The SCX2500LF has a ground contact pressure of 117.2 kPa in liftcrane mode and 133.4 kPa in luffing towercrane mode, ensuring stability and minimizing ground impact across various surfaces. The operating weight varies based on configuration: approximately 210 tons in liftcrane mode (with a 250-ton hook block) and 239 tons in luffing towercrane mode (with a 60.95-meter tower, 60.95-meter jib, and 80-ton hook block).

Safety features include an advanced Load Moment Limiter (LMI), which displays real-time lifting data such as load weight, radius, and capacity, and issues alerts if conditions become unsafe. The crane also incorporates emergency stop switches, travel and slewing alarms, and boom and hook height limiters, ensuring a high level of operational safety.

Overall, the Hitachi-Sumitomo SCX2500LF offers a powerful and adaptable lifting solution, suitable for various applications, including construction, infrastructure development, and industrial lifting tasks. Its combination of long reach, heavy lifting capability, and safety-oriented design make it a reliable choice for complex projects.
